[kingsleyh]

hmm thanks - first time I've seen this issue

[kingsleyh]

I tried to put a fix for this - but not really sure how it occurs - I think it might be an issue with the baked file system shard or some kind of timing issue during building. I thought the fix had worked but we still get this happening intermittently on the gihub build actions CI - although we don't see it on the circleci build. So still unsure what the problem is - it's intermittent tho

#386 fixed it for me though
